Does anyone know if Yonex MP-99, MP-100 or AT700 are available in Vietnam?
If so, do you know the prices? Are there fakes to look out for?

Thanks
Poor man who can't afford US prices.

There are fakes to look out for in Vietnam. I remember some of my friends who went to Vietnam only to come back with fake racquets. None of them were real...they paid around $20 - $40 for them. So just use caution.
